Summary

Animas High School is a small public charter high school in Durango, Colorado, serving 249 students in grades 9–12 under the State Charter School Institute. The school presents an unusual academic profile: it shines in science and reading while struggling in math. In 11th grade, 47.1% of Animas students were proficient in science on the CMAS assessment, far exceeding the state average of 24.8% and outpacing nearby Durango High School (38.8%), Bayfield High School (18.3%), and Ignacio High School (12.5%). Reading and writing are also strong, with 68% of 11th graders proficient on SAT Reading and Writing versus 60% statewide.

Math is the clearest weakness. Only 19% of Animas 11th graders scored proficient on SAT Math, compared to 32% statewide, and 9th- and 10th-grade math proficiency has dropped sharply since 2023-2024. By contrast, Durango High School posted 10th-grade math proficiency of 54% in the most recent reporting. The school's statewide ranking has slipped from the 78th percentile in 2021-2022 to the 42nd percentile in 2025-2026, a decline that aligns with the falling math scores. Still, Animas outperforms most rural neighbors on overall outcomes and posts strong results for its economically disadvantaged students, who ranked in the 77th percentile statewide in 2023-2024.

Attendance is a standout advantage. Only 16.1% of Animas students were chronically absent in 2024-2025, versus 28.4% statewide and rates above 40% at Bayfield High School, Ignacio High School, and Durango Big Picture High School. The graduation rate of 90.3% exceeds the state average of 85.6% and most nearby schools, and the 10.9:1 student-teacher ratio offers more individualized attention than Durango High School's 16.1:1. For parents weighing options, Animas offers a personalized, engaging environment with strong science and literacy outcomes—but math is both the school's greatest weakness and its clearest opportunity for improvement.
